LOADING APPARATUS.

Reling of application Serial No. 446,769, led February 2'1, 1.921. Thisapplication filed October 4, 1922. Serial No. 592,387.

T all whom t may concern: 'Y

Be it known that I, SAMUEL HURWITZ, a citizen of Russia, residing at LosAngeles, in the county of Los Angeles and State of California, haveinvented new and useful Improvements in Loading Apparatus, of which thefollowing is a specification.

It is the object of this invention to pro vide a loading apparatusparticularly adapted to be employed for loading heavyob jects on totrucks and the like.

As stated in my application Serial No. 446,789, led February 21, 1921,and not prosecuted to an allowance,this invention consists essentiallyof a frame which is preferably a vehicle frame and platforms thereonadapted to be raised and lowered with relation to the frame.y Vindingmeans are provided upon the frame and are preferably manually actuatedthrough a Vsuitable reduction gearing. Thecables received upon thewinding means are adapted to be connected to one of the elevatingplatforms for raising the same or may be extended beyond the apparatusandconnected to any object which it is desired to draw toward theapparatus in order that it may be placed upon one of the elevatingplatforms and then raised as previously described.

The invention will be readily understood from the following descriptionof the accompanying drawings, in which Figure 1 is a side elevation of aloading apparatus constructed in accordance with se the invention.

Fig. 2 is a rear view of the same.

Y Fig. 3 is a top plan view of the apparatus.

Fig. 4 is a horizontal section on the line 4 4 of Fig. 1.

e0 Fig. 5 is a detail section on the line 5 5 of Fig. 2.

The main frame of the apparatus comprises a base 1 preferably mountedupon rollers or casters 2. Vertical guide means project upwardly fromthe base and are shown as comprising uprights 3 at. the respective sidesof the base and spaced from the rear end of the same. Braces 4 connectthe uprights 3 and the base at its rear edge.

Loading platforms are positioned above the base 1 at the front ofuprights 3 and are shown as comprising an upper platform 5 havingdepending uprights 6 at the respective sides of its rear edge. A lowerplatform 7 is provided with similar uprights 8 at the respective sidesof its rear edge, and

these vlatter uprights extend upwardly through a slot 9 provided inplatform 5. Suitable braces 10 and 11 connect platform 5.andits uprightsand platform 7 and its 6o uprights respectively.

The platforms in their lowered vposition are shown in Fig. 1, and theuprights Y3 of the main frame extend an appreciable distance above theplatforms when in this'posi- 65 tion, in order to form guide meansV forthe uprights ofeither one of the. platforms as it is elevated. For thispurpose brackets 12 extend forwardly from the respective uprights 3 andare provided with rollers 18 l70 engaging the front of the respective`uprights 8 adjacent the upper ends of the same when the platforms are inlowered position,l and in similar. manner brackets 14 extend rearwardlyfrom uprights 6 adja- `75 cent the upper ends of the same and arelprovided with rollers 15 'engaging the rear surfaces of uprights 3.Brackets 16 and 17 also extend rearwardly from the lower ends ofuprights 6 and 8 respectively and are r,80. provided with rollers 18 and19 engaging the front surfaces of uprights 3.y Y

Y The means for raising and lowering one or theV other of the platformsincludes a frame Y 20 extending rearwardly from the cross 85 plates 21connecting uprights 3 and having a suitable shaft 22 journaledtransversely therein and carrying winding drums 23. A suitable reductiongearing is mounted in frame 20 and is shown as comprising shafts 90 24one above the other. Small gears 25 on the respective shafts mesh withlarge gears 26 upon the next upper shafts, and the uppermost small gearsrotated by large gears G- on shaft S mesh with large gears 27 upon 95shaft 22, so that rotation of the lowermost shaft 24, as by means of ausual crank 28, will actuate shaftA 22 through the reduction gearing. Apawl and ratchet 29 and 29a is provided for the lowermost shaft 24, soas to hold the platforms in elevated position.

Cables 30 wound upon drums 23 are adapted to be engaged by means ofhooks H, H

in suitable eyes 31 at the lower ends of up- V'105 rights 6 and 8, inorder that one or the other or both of the loading platforms may beelevated. When, however, it is desired to employ the winding means yfordrawing an object to be raised toward the apparatus, the cables 30 maybe passed over guide rollers 32 so as to extend in one direction, or arepassed around guide yrollers 32 or around guide rollers 33 arranged atan angle thereto so that the cables Will extend in a differentdirection. When the cables are thus passed over the guide rollers, theymayo tionally berpassed beneath rollers 34 carried Iby pivotally mountedlatch arms 35 mounted upon platform 7. These latch karms are normallyspring retracted vas shown vsaid .platforms fo-r elevating the same.

2. A loading apparatus comprising la frame, upper and lower platformsvertically movable relative thereto, and Winding means carried by saidvframe and having cables adaptedto engage one or the other of saidplatforms for elevating-the same.

3. A loading apparatus comprising a frame, platforms vertically movablerelative thereto, Winding'mea-ns carried by said frame, and cable guidesthereon, said Winding means having cables adapted to engage either ofsaid platforms for elevating the same or `'to extend beyond said guidesto .engage an object to be moved to said loading apparatus.

4. A loading apparatus comprising a frame, yplatforms vertically movablerelative thereto, Winding means carried by said frame, and a reductiongear foi` operating .the same, said winding means having cables adaptedto engage either of said platforms for elevating the same.

5. A loading apparatus comprising a frame, a Vplatform verticallymovable relative thereto, Winding means carried by said frame, and cableguides thereon extending in different directions, said Winding meanshaving a plurality of cables adapted to engage said platform forelevating the same or alternatively to extend about either of saidguides :to engage objects to be drawn to said loading apparatus fromdifferent directions.

6. A loading apparatus comprising .a frame, a platform verticallyfmo-vable relative thereto, Winding means carried by said frame, cableguides thereon, said -Windin'g fmeans Vhaving cables adapted to.engagesaid platform for .elevating the same Vor to extend beyond saidguides to Yengage an object -to'be moved -to said loading apparatus, andmeans for .lockingsaid platform relative 'to said frame, :said meansbeing actuated by said cables co-operating With said guides.

In testimony whereof I have signed my namelto this specification.
